YANJIE SHI: Hi, I'm Yanjie from Vouse.
We are a design agency based in Singapore.
Vouse is an assemblage of architects, programmers, and game designers.
We use game engines in the architectural
and built environment sector on a wide range of projects,
ranging from residential, to commercial, and even to heritage.
Our projects are often tailored specifically
to the needs of the client.
And we deliver from the conception stage
all the way to development of the software,
as well as maintenance of the project after it's completed.
Today I am very happy to share with you
our project with Changi Airport Group, the Changi Airport
digital twin.
Vouse has always been a partner of Changi Airport Group since 2017.
And we developed a digital twin of Changi Airport
over the past two years together with Mr. Ao Chin Wen and his colleagues
from T5 Planning The digital twin is around 1,200 hectares.
And that is roughly the size of 3,200 football fields.
Our approach to digital twins is to build a data integrated model.
We stream in live operational data into the 3D model.
And we use that as the base to develop applications
for different end users of the airport.
The reason that we chose Unreal Engine
is because of its ability to provide real time graphics by the same time
we can integrate with backend databases.
And this allows us to scale with the size of the project.
Throughout the two year period, we deployed
to different platforms and applications
from the same project file.
The base model was built based on CAD and BIM information.
The 3D models are constructed modularly
and assembled in Unreal Engine to take
advantage of the many optimization tools,
often used for open world games.
These includes instancing, as well as the foliage tools.
This is important, because on a project of this scale
your performance is key.
Using geo referencing we aligned the model with real geo
coordinates that allows for integration with sensors and data.
With Blueprints we view integrations with the Changi backend databases
that streams in live data and projects them
onto the model in real time.
To talk a bit more about the technical details
let me invite the next speaker, Pun Hei, who
is our senior developer on Vouse.
PUN HEI CHIU: Hi, I'm Pun Hei, a senior software developer at Vouse,
talking about our application which uses aircraft transponder
data to visualize the position and movement around a digital scale
model of Changi Airport in Unreal Engine 4.
The application can display plane position
and additional information in real time, relayed from a server
in the airport.
It also allows users to play back historical simulation records
transmitted from the server itself or from records
stored in a local database.
Going forward, our future plan is to integrate
as much information as possible into the application
to serve as a central hub of information for monitoring purposes,
such as arrival and departure times at each gate, human traffic
counters, temperature and humidity sensors, and so on.
YANJIE SHI: Thank you, Pun Hei.
That was an example of deploying the digital twin on a macro scale.
On a more micro scale we investigated the role in traffic infrastructure
from the angle of the actual user by deploying the digital twin
on to a driving rig.
We showed that a detail level can be achieved with ground level
signage and markings.
With this, end users such as technical staff and operators
of the airport who may not be familiar with architectural drawings
can be engaged to test out the digital twin.
This opens up opportunities with the complex tools
that Unreal provides to build scenario training and design
validation applications.
This is especially important in today's world
where digitization and remote training
become increasingly important.
The digital twin is currently deployed internally
in Changi Airport.
It is meant to be a live model, which is consistently updated
with new content and features.
This project serves as a foundation for Changi Airport Group
to continue exploring digital transformation
in the domain of airport planning, simulation, and operations.
Thank you for listening to my presentation.
I wish you a pleasant evening, and please enjoy the rest of the events.
Thank you.
